The actress opened up to Vanity Fair about her reasoning for not taking selfies when asked by fans on the street. She stated “For me, it’s the difference between being able to have a life and not. If someone takes a photograph of me and posts it, within two seconds they’ve created a marker of exactly where I am within 10 meters. They can see what I’m wearing and who I’m with. I just can’t give that tracking data.”

But just because she turns down the photo op, it doesn’t mean she won’t take the time to talk with some of her biggest fans.

“I’ll say, ‘I will sit here and answer every single Harry Potter fandom question you have but I just can’t do a picture.’ I have to carefully pick and choose my moment to interact. When am I a celebrity sighting versus when am I going to make someone’s freakin’ week? Children I don’t say no to, for example,” she continued.

She also made it a point to share that the “Harry Potter” fandom has turned into obsession, and it very often making her question if this is the life for her.

She is 26 years old and said growing up in the limelight is much different with social media in the game.

“I was finding this fame thing was getting to a point of no return. I sensed if this was something I was ever going to step away from it was now or never,” she recalled to Vanity Fair when discussing that she considered quitting acting while attending Brown University. “By the time she reached adulthood, she tells her friend, “It dawned on me that this is what you’re really signing up for.”
